Corrective Action
RUN
Read the individual information of the error using
RUN
the GX Developer, check the program correspond-
ing that value (program error location), and make
correction.

• When performing the online module change in a
multiple CPU system, correct the program so that
access will not be made to the intelligent function
module controlled by the other CPU.
• When accessing the intelligent function module
controlled by the other CPU in a multiple CPU
system, set the online module change setting to
be "disabled" by parameter.
